WhatsApp for Sony Xperia

WhatsApp uses its own basic in-app camera, which bypasses Sony's image processing and heavily compresses the result, so it never matches the dedicated Camera app on the Xperia 1 VII. Instead of shooting from inside the chat, open the Sony Camera app, take the shot, then attach it in WhatsApp via the gallery/photo icon. For the sharpest result also set Settings > Storage and data > Media upload quality > HD in WhatsApp. See how others solved this on Reddit

WhatsApp uses its own basic in-app camera instead of Sony's Photo Pro app, so it never accesses the full sensor quality your Xperia is capable of, and it also compresses anything you send. For sharp results, take the photo first with the stock Sony camera app, then in WhatsApp tap the attach (paperclip or +) icon, choose Document instead of Gallery, and send the image file that way to skip WhatsApp's heavy compression.

First update WhatsApp from the Google Play Store, since outdated builds can crash on Sony's stock Android. If it still closes, go to Settings > Apps > WhatsApp > Storage & cache and tap Clear cache (not Clear storage, which deletes local chats), then reboot the phone. Also set Settings > Apps > WhatsApp > App battery usage to Unrestricted so the system isn't killing it in the background. See how others solved this on Reddit

WhatsApp uses its own basic in-app camera that bypasses Sony's camera processing, so shots look soft and noisy compared to the stock app. For good results, shoot with Sony's Camera (Photo Pro) app first, then in WhatsApp tap the attach (paperclip) icon, choose Gallery, and send the photo from there. Also reduce compression by going to WhatsApp Settings > Storage and data > Media upload quality and selecting HD. See how others solved this on Reddit

WhatsApp captures through its own basic in-app camera, which doesn't use the Pro-I's 1-inch Exmor RT sensor or Sony's image processing, so shots look soft and over-compressed. For photos you care about, shoot with the stock Photography Pro app, then in WhatsApp tap the paperclip and choose Document (not Gallery) to send the image at full resolution without re-compression. You can also reduce compression on normal sends via WhatsApp > Settings > Storage and data > Media upload quality > HD. See how others solved this on Reddit

This is usually a permissions or audio-routing issue rather than a hardware fault. Go to Settings > Apps > WhatsApp > Permissions and make sure Microphone is set to Allow, then place a normal phone call to confirm the mic works system-wide. If it still fails, clear WhatsApp's cache under Settings > Apps > WhatsApp > Storage > Clear cache and reboot. If the mic works in regular calls but not in third-party apps, make sure both Android and WhatsApp are fully updated, since the fix usually arrives in an app or system update.

This is a known WhatsApp + Bluetooth issue on Xperia rather than a hardware fault: tapping answer inside the app often works even when the headset's physical button doesn't register the call. Make sure WhatsApp has the Phone and Microphone permissions under Settings > Apps > WhatsApp > Permissions, then re-pair the device under Settings > Device connection > Connection preferences > Bluetooth. Update WhatsApp from the Play Store, since several call-routing bugs have been fixed in newer builds. If a specific car or earbud still fails, toggle Bluetooth off and on right before answering to force the audio to re-route. See how others solved this on Reddit

First confirm it isn't hardware: record a clip in the Sony Recorder app and play it back. If that sounds fine, the problem is app-side. Revoke and re-grant the mic permission under Settings > Apps > WhatsApp > Permissions > Microphone, then force-stop and reopen WhatsApp. Set WhatsApp to Unrestricted under Settings > Apps > WhatsApp > App battery usage so Sony's power management doesn't throttle background audio, and make sure no case or screen protector covers the bottom microphone. Updating WhatsApp from the Play Store also clears known mic-processing bugs. See how others solved this on Reddit

On your old Android phone, open WhatsApp and go to Settings > Chats > Chat backup, then tap Back up to Google Drive using the same Google account you'll sign into on the Xperia 10 IV. Install WhatsApp on the Xperia, verify the same phone number, and when prompted choose Restore to pull the backup down from Google Drive. Make sure both phones use the same Google account and that the Xperia is connected to Wi-Fi before restoring. See how others solved this on Reddit

Callers often report you sound muffled or distant on WhatsApp even though regular phone calls are fine. First confirm the hardware is OK by recording a clip in the Recorder app and listening back. Then make sure WhatsApp has clean mic access in Settings > Apps > WhatsApp > Permissions > Microphone (set to Allow), and gently clean the small bottom mic hole next to the USB-C port, since lint there muffles the sound. If it persists, try toggling Bluetooth off (a connected accessory can route the mic away) and reinstall WhatsApp to rule out a corrupt install. See how others solved this on Reddit
